NICOR''s TGLS2 Selectable Backlit LED Flat Panel Troffer features the latest in LED technology with Selectable Wattage and Selectable Color Temperature, all in one unit. Each luminaire features two selectable switches to control color temperature (3500K, 4000K, 5000K) and brightness (Standard, Medium, High). The ultra-slim flat panel measures just 1.6-inches in depth (including the driver) making it lightweight and easy to handle during installation. The backlit LED system produces a brilliant and natural radiance while reducing glare to eliminate shadowing and uneven lighting often seen in cheaper models. The precision-engineered polystyrene lens is sealed to the frame to keep out dust and debris allowing for direct contact with insulation (IC-Rated). The TGLS2 includes an integrated dual-voltage driver (120-277VAC) with full-range dimming (0-10V) capabilities and a tested lifespan of over 54,000 hours of operation. The TGLS2 is offered in 1x4, 2x2, and 2x4 configurations and arrives ready to install right out-of-the-box. Optional accessory kits for surface mounting or drywall framing are sold separately. All TGLS2 fixtures are protected by NICOR''s 5-year limited warranty.
